Like this:

Someone famous must be on my bus,
People look around and fuss.
I wonder who this celeb could be,
And are they sitting near to me ?
Then I notice the CCTV,
Broadcasting for all to see.
My stubbled chin and thinning hair,
On the security screen up there.
I don’t mind that people stare,
As I slump in my chair.
With my face tired and drawn,
Barely concealing a yawn.
But what I really do regret,
Is that I’m not captured at my best.
I wished I looked more composed,
And wasn’t on CCTV picking my nose.
